This-invention relates to flier-spinning, roving and analogous machines, having spindles which are'carried by footstep bear ings and are provided with intermediate bearings offering lateral support, the vfliersandihencealsothe rail A and resultantly being attached to'the heads of the spindles.

In machines of this type trouble is often elear of the necks E of thefliers which are experienced at high speeds owing tothe vibration arising therefrom, and this invention has for its] objectto secure steadier iun-- ning or the spindles; at normal speed aswell "as to enable a greater spindle sp'eedtobe obtained 'without excessivefvibrat'ion;

Accordingly, fth'e' invention consists in p Qviding a flier'spinni'ng' roving or analo gcus maclnne of'the type referred to withoverhead means offering support to the tops of the, fl ers dur ng the spinning, roving or other 'operlation, and m eans for withdrawlng such supportni order to pernnt the;

doffing operation to be performed.

Two convenient constructional forms of the invention are illustrated by way of example in the accompanying drawings, in which Figure 1 is a sectional elevation of part of the upper portion of a flier roving machine, and Figure 2 is a plan view of part of the overhead rail showing a modified form of slot therein and a correspondingly slotted bush. Figure 3 is a front view of part of the upper portion of a machine and Figures 4 and 5 are a sectional elevation and plan view, respectively embodying an alternative design to that indicated by Figures 1 and 2.

Referring to Figure 1, A is an overhead rail located above the tops of the fliers B and formed with apertures C at intervals corresponding with the pitch of the fliers, in each of which apertures C is fitted nonrotatably a flanged bush D adapted to serve as a bearing affording lateral support to the upwardly projecting nee; E of the flier;

the spindles (not shown) in this case being f supported at their lower extremities.

The rail A is supported at intervals by the forwardly. and horizontally disposed carrier members F which are secured to the heads of downwardly extending vertical stems G adapted to slide in guide brackets H bolted or otherwise suitably secured to the top rail or beam J of the machine.

Below said stems G and extending longitudinally of the machineis a rock shaft K upon which are keyed cams or eccentrics L,

one below each stem G, which when the ls ha'ft 'K is :rocked, eontactfwithj the lower 1. extremrtles' of said stems and d splace them vertically upwards prior to the performance i-of. the .doffing'operation'i In their upward their manipulated together with the spindles todoff thebobbins; In this constructionif the spindles are' moved angularllyj forward C' and the bushes Di may; be co r respondingly slotte'drad ally asat D in order i -lib" enable thefthrieadto" pass clear of; the .bushes and Tall when' the spindles are moved :to. doff; i' Duringith e-spinningjoperation the lateral support afforded the bushes or bearings D to the necks of the fliers materially decreases vibration at high speeds and enables the spindles to be run at greater velocity than heretofore without detriment to the machine and without increased vibration.

Referring now to Figures 3, 4t, and 5, each of the apertures C in the rail A is rebated or stepped in formation, the smaller diameter being uppermost, and each of the bushes D is correspondingly stepped eX- ternally and is'held against rotation by means of a pin M which contacts with the head of a set screw N screwed into the underside of the rail A.

In this case instead of withdrawing the bushes D from the necks of the fliers the rail A is raised clear of the bushes each of which is retained in position upon the neck E of its corresponding flier by means of a split ring or collar 0 sprung over and embracing said neck E on top of the bush D The rail A is supported on vertically movable members F, G, sliding in guide brackets H bolted to the beam J cams or eccentrics L on camshaft'K actuating the stems G.

This construction of stepped bush and .tures O in the'rail A maybe slottedradially aperture isfound to enhance the steadiness of the spindle mounting at high spindle speeds. I We claim 1. In flier-spinning, twisting, roving and analogous machines; overhead means offering support to the tops of the fliers during the spinning, roving or other operation, and

means for withdrawing said support in order to permit said spindles to be dofled.

\ rail in order to permit said spindles to be 3. In flier-spinning, twisting, roving and analogous machines, an overhead rail apertured correspondingly with the spacing of the spindles, bearing bushes fitting said apertured rail and engaging the tops of said fliers, carrier members supporting said overhead rail, said carrier members being mounted slidably in a vertical direction, and means for raising said carrier members and said overhead rail in order to permit said spindles to be dofled. I i

4. In flier-spinning,twisting, roving and analogous machines, an overhead rail apertured correspondingly with the spacing of the spindles, said overhead railaflording lateral support to said fliers during-the spinning operation, bearing bushes fitting in said apertured rail and engaging the tops of said fliers, V substantially right-angled carrier members supporting sald overhead rall, said substantially right-angled carrier. members lateral support to said fliers during the spinning operation, bearing bushes fitting in said apertured rail and engaging the topsof said fliers, substantially right-angled carrier members supporting said overhead rail, said substantially right-angled carrier members being mounted to slide vertically, and cam operated elevating mechanism co-acting with said substantially right-angled carrier members and said overhead rail at appropriate times for the purpose speolfied.

In testimony whereof we alfix our slgnatures.
